HOW AIR HEAD COMPOSTING TOILETS WORK

COMPOSTING TOILET THAT DIVERTS LIQUIDS AND SOLIDS

The “Air Head” Composting Toilet works simply. By separating liquids from solids, the volume of solid human matter is significantly reduced. Air Head’s approximate 19 litres capacity means that up to a season’s worth of weekend use may be held. (Based on solid matter volume for two persons’ use twice every weekend for five months: 80 uses). A live-aboard couple can expect 60 uses (one month) before they’ll have to empty the solids tank.

Much like a household toilet the “Air Head” Composting Toilet has a bowl and an actuator which provides a “flush.” The main difference is the “Air Head” Holding Toilet’s waterless operation. A paper bowl liner acts as a carrier for solid matter on its way to the solids tank.

SOLID MATTER TANK AND URINE TANK

The solid matter is separated and agitated, thereby decomposing it into a non-offensive state inside the large tank. Additionally, the unit has an integral 12-volt fan that provides a constant negative pressure to pull moisture out of the living space. Even after long lay-ups, there is no “holding tank” smell when you come aboard.

Liquids are collected in the smaller forward tank. Its wide-mouthed aperture will keep the contents emptying smoothly into any standard commode. The liquid tank will hold approximately four days use per person if used exclusively. A low-profile bottle is also available that holds about half the volume of the standard bottle.

ADDITIONALLY

The “Air Head” may be integrated with an existing holding tank system, creating holding capacity for both solids and liquids far beyond what many medium and small boat owners are used to. This is because the tanks take on no flushing water and are free to hold just what they need to.

DIMENSIONS

The Air Head Composting Toilet has a small footprint. Here are the dimensions of the dry composting toilet.
